The DA9130-XXRT2 from Renesas is an Automotive-Qualified Power Management IC that is designed for powering CPUs, GPUs, and DDR memory rails in single in-line pin package modules, mobile, portable, and consumer applications. It requires an input voltage of 2.8 - 5.5 V, provides an output voltage of 0.3 - 1.9 V, and an output current of up to 10 A. This AEC-Q200 Grade 2-qualified power management IC (PMIC) consists of a dual-phase buck DC-DC converter, bias supervision oscillator, a digital core OTP memory register chip, and interfaces. The buck converter of this IC has two voltage registers with one defining the normal output voltage while the other offering an alternative retention voltage. It uses GPI or other control interfaces to select voltage levels to guarantee maximum flexibility according to the specific host processor status in the application.
This PMIC uses dynamic voltage control scheme for adaptive adjustment of the output voltage, depending on the load, thereby increasing the efficiency when the downstream circuitry enters low-power or idle mode. It also has fully programmable soft-start setup that limits the inrush current flowing from the input to provide a slope-controlled output voltage. This power management IC is available in a surface-mount package that measures 3.3 x 4.8 mm.
